Because the endpoint does not enforce authentication and lacks proper request size or resource limits, an attacker can upload large or malicious files that consume CPU or memory, leading to resource exhaustion and a denial of service. The ability to process files also potentially exposes sensitive data contained in the uploaded files or in the service\u2019s internal processing logs, violating the application\u2019s documented security policies.", "risk_and_exploitability": "With a CVSS base score of 7.5, the vulnerability is considered high severity. No EPSS data is available and it is not currently listed in the CISA KEV catalog, but the lack of authentication makes exploitation trivial to anyone who can reach the endpoint. An attacker can simply craft large files or repeated requests to trigger a DoS, and the endpoint\u2019s open processing may also reveal internal information. The likelihood of exploitation is high due to the obvious lack of access control."}}}}, "created": "2026-03-29T20:31:14.679898+00:00", "updated": "2026-03-30T06:58:02.732997+00:00", "vendors": ["parisneo", "parisneo$PRODUCT$parisneo/lollms"]}
